I confess I may have been a tad extreme to make my point.
Still, it seems to me that using a tormek to end up freehand sharpening on the rounded corner of the stone is precisely some kind of a violin / boxing gloves situation : you no longer use the controlled angle which makes the beauty (and most of the sales pitch) of the Tormek, you round up the edges of the stone a lot and yet you will still be applying pressure on just a tiny area of the edge which is a recipe for disaster. Again, I'm not saying it can't be done, I'm saying it's not the intent. I've only seen wootz's technique achieving a comparable level of finish to what you can do on a tormek with convex shaped knives, at what (financial and learning) cost.
I have a small abrasive belt knife sharpener which cost me roughly the price of a Tormek stone, with a "slack" setting where you contact about an inch of the curved blade at a time. Just from a pure physics standpoint, one easily understands it is much more suited to the task. And you get a tool to reprofile blades to finish on the tormek - as long as you don't reprofile hundreds of knives a year - or sharpen lawnmower blades.
